large sewage water treatment equipment stainless steel screw filter press

Product Name: large sewage water treatment equipment stainless steel screw filter press

• Apply to the dewatering for high and low consistency sludge.There are no need to build the concentrated tank and  storage pool,which will reduce the fees of construction, the emission value of Phosphorus and  the producing of anaerobic stinkdamp,when you deal with the low  consistency sludge(2000Mg/L).
• No blocking, Thereby reducing the water consumption,saving the water's fees,and reduce the inner cycle for washing.
• Electric control cabinet, the mixture of flocculant and dewatering sysytem form the integration,not reduce the floor space,but easy to installing.
• The machine keep working in a fully closed structure,with the features of stable and timely,reduce the bad smell to the lowest level,thus improve the working environmet of workers.
• Automatic running 24 hours a day,reduce the labour intensity of workers.
• Lowest operating speed for screw shaft,and only for 2-3 rpm,lower power consumption,without obvious shake and noise in the site.
• SS304 stainless steel for the machine body,increasing of service life farthest.Replaceable parts only for screw shaft  and moving ring,long service life.
• Less timeand simple operating for everyday's maintenance.

Structure Principle of  screw filter press  :                                

• The fixed ring and moving ring stack each other for screw run through and form the main body of dewatering machine finally.
• Between fixed ring and moving ring form the small gap to filter the filter liquor.The inner space is filled with the flocculent particles between the screw and rings,then the screw extrude flocculent particles and inform the mud cake during transporting to the outfall.
• The screw rotate and push continually,which drive the moving rings moveing by multi direction,thus clear the gap and avoid blocking.

screw filter press Principle of Dehydration: 

      After the sludge accomplish gravity concentration in thickening system,then transport to dewatering system.The gap and screw pitch get smaller and smaller during the transport,with the plate's obstruction,it inform the bigger inner pressure and the volume get smaller,achieve the purpose of fully dewatering finally.
